safety apparatus in its present embodiment I is made up of a plurality of'car supporting 'and brake actuating units designated generally at "T, and a pair of truck embracing'yokes designated at Y. As illustrated to advantage in Fig. 4, each unit T com prises a pair of s aced hangers 15 formed at oneend with anges 16 through which fastening membeis are adapted to exend for securing the hangers in depending relation to the under side of a car. The opposite ends of the hangers are recessed at their'confronting sides to loosely accommodate abearing member 17. Rotatably fitted in, the bearing member 17 is a roller 18 having. the opposite ends thereof provided with axle ends 19 which are loosely fitted in elongated openings 20 formed 'inthe hangers 15. Theroller 18 is tapered in diameter from one end to the other, with the large end formed with an annular flange 21 that is adapted to function in the same manner as the flange of one of the" car wheels. Thebearing member 17 is provided 'with an arm 22 that extendsbetween the hangers 15 so as to move with the member. As illustrated t0 I advantage in Fig. 6, the free end of the arm 22' is provided with "a circular extension. 23 that is adapted to workwithin an opening- 24 formed in a cross bar-125" connecting the hangers at their flanged ends. The arm 22 is also provided with a lateral projection 26 adapted to engage the stem 27 of a brake valve V, the latter being interposed'in the train line L of an air'brake system.

The yokes Y, as illustrated to advantage in Fig. 1, are of rectangular outline and are secured to "the underside of the car and in spaced relation to each other so as to'loosely embrace thewheel truck and the brake beams indicated at 5 28,? the yokes being provided with hooked extensions 29 for supporting the. brake beams] As shown in Fig. 2, the yokes Y are arranged longitudinally o'f the car, and are adapted-to be so designed as to ment of thevvheel truck in allowing the wheelsto conform to fthecurvature of the- -track, but tov prevent, excessive movement thereof such as when the-car is derailed. It is a well known fact that in the derailing of cars the wheel trucks often occupy transverse positions with respect 'to a car or track rail, thus efi'ecting destruction of the rails allow'of the usual pivotal or swinging moveand ties and enhancing the possibility of the car overturning. By the provision of the In the applied position of {each car sup- I portingv and brake actuating unit, the hangers 'are secured to the under side of the car adjacent to the Wheel truck so as to support the corresponding-roller 18 in a position directly above the ,correspondin trackrail as clearly, shown 'in 'Fig] 3; n the present instance, v.Ihave provided four. such units arranged at .the four corners of a wheel truck and so that two of the rollers overlie one'track'- rail, and the remaining. rollers overlie the other track rail. The-length ofv the hangers 15 is such that the rollers 18 are supported in spaced relation to the track rails so that theyare normally outof contact therewith. By virtue of the elongated open- 24, the rollers are permitted to gravitate to such position thatthe arms 22 are in 'suchia position that the projeetions 26 are out of engagement with the steins27 of the valvesV; The extensions 23 are OffSllCh a length that they are retained Within the openings20 in the lowered position of. the rollers 18, thereby guiding the arms when moved upwardly, so that the projections 26 will engage the valve stems 27 In practice, the safety apparatus during thenormal operation of the wheel truck remains inactive. -However, when thejwheels.

of the truck are derailed, the rollers 18 are lowered into'contact with the track rails thus; providin an aukiliary'support for maintainin t ecar in rollin .engagement' 'with' the rails of the track. s soon'as the car is: lowered by the disengagement of the wheels, the'rollers are moved upw'ardlywith in the hangers thereby eflecting an upward movement of the arms 22 to cause the pro-- jections 26 to en age the stems 27 and thus -to effect the bleeding of the train line with a subsequent actuation of the air brakes. It is to be understood that all of the rollers operate simultaneouslg to effect an opening ofall of the valves so I obtained to insure ofthe application of the brakes. I V v -Fro'm the foregoing operation it will be clearthat should any wheel truck ofjacaror v a train of cars be derailed the apparatus automaticallyfun'ctions to actuate they-brakes train is prevented.

and thereby bring'the train toa stopfso thatthe complete derailing of theentire! car or. 7 p the rollers 18 is such as to prevent the complete derailing of that The formation of portion ofthe car supportedbythe derailed truck, it being understood that because ofthe tapered formation of the rollers and the roller,
